Provided by: sipcalc_1.1.5-1_amd64 NAME sipcalc - IP subnet calculatorSYNOPSIS sipcalc [ -abcdehiInrsStuvx46 ] - ]>DESCRIPTION Sipcalc is an ip subnet calculator consisting of two parts. A plain text based console version, and web (cgi) based counterpart. This manpage only addresses the console based version. Sipcalc, in it's simplest form takes an ip-address and a subnet mask on the commandline and outputs information about the subnet. Sipcalc has support for both IPv4 and IPv6 addresses. Sipcalc can take input in three forms, an ip-address/netmask, an interface or via stdin using the special character -. Address-IPv4 Address must be given in the "standard" dotted quad format, ie.: xxx.xxx.xxx.xxx and prepended with a netmask the can be given in three different ways: - CIDR, ex. /n where n >= 0 = 0 cat(1) ing a list of addresses stored in a file to sipcalc. Each line sent to sipcalc should contain one address/netmask or interface. Any number/combination of Address and Interface arguments can exist on the commandline, however, the special character - must be the first argument or it will be parsed as an interface. All options following the - character will be discarded. Features (IPv4) - * Multiple address and netmask input formats. * Retrieving of address information from interfaces. * Classfull and CIDR output. * Multiple address and netmask output formats (dotted quad, hex, number of bits). * Output of broadcast address, network class, Cisco wildcard, hosts/range, network range. * Output of multiple types of bitmaps. * Output of a user-defined number of extra networks. * Multiple networks input from commandline. * DNS resolutions of hostnames. * Parsing of a newline separated list of networks from standard input (STDIN). * The ability to "split" a network based on a smaller netmask, also with recursive runs on the generated subnets. Features (IPv6) - * Compressed and expanded input addresses. * Compressed and expanded output. * Standard IPv6 network output. * v4 in v6 output. * Reverse dns address generation. * DNS resolutions of hostnames. * The ability to "split" a network based on a smaller netmask, also with recursive runs on theIPv6 CIDR Calculator - webtrafficexchange.com
IP-undernätskalkylatorgjord med ❤️ avInnehållsförteckningVad är subnät?Ett subnät hänvisar till en del av en IP-protokollsvit (internetprotokollnätverk). Ett IP-nätverk är en grupp protokoll som används av Internet. TCP/IP (Transmission Control Protocol/Internet Protocol) är det vanligaste namnet.Hur fungerar subnät?Subnetting hänvisar till handlingen att dela upp ett nätverk i minst två distinkta nätverk. Routrar är enheter som tillåter trafikutbyte mellan undernätverk samtidigt som de fungerar som en fysisk gräns. Medan IPv4 fortfarande är den mest populära tekniken för nätverksadressering, växer IPv6 i popularitet.En IP-adress består av ett routingnummer (prefix) och en värdidentifierare (vilofält). Ett vilofält hänvisar till en identifierare som är unik för en viss värd eller nätverksgränssnitt. Classless Inter-Domain Routing, (CIDR), är ett vanligt sätt att uttrycka ett routingprefix. Detta fungerar för IPv4 såväl som IPv6. CIDR används för att skapa unika identifierare som kan användas för både enskilda enheter och nätverk. Subnätmasker är också möjliga för IPv4-nätverk. Dessa undernätsmasker uttrycks ibland i punkt-decimalnotation som ses i räknarens "Subnät"-fält. Varje värd i ett undernätverk har samma nätverksnummer, inte värd-ID, som är unikt för varje individ. Dessa subnätmasker kan användas i IPv4 för att skilja mellan värdidentifieraren och nätverksnumret. IPv6:s nätverksprefix har en liknande funktion som IPv4-subnätmasken. Prefixlängden är antalet bitar i en adress.Innan CIDR introducerades kunde IPv4-prefix erhållas direkt från IP-adressen baserat på adressens klass (AB eller C). Nätverksmasken påverkar också intervallet av IP-adresser den innehåller. Men för att tilldela en adress till en nätverksadress måste man ha både dess adress och dess mask.Subnät diagram?Nedan finns en tabell över typiska undernät som IPv4 använder:Prefix size Network mask Usable hosts per subnet/1 128.0.0.0 2,147,483,646/2 192.0.0.0 1,073,741,822/10 255.192.0.0 4,194,302/11 255.224.0.0 2,097,150/12 255.240.0.0 1,048,574ArtikelförfattareParmis KazemiParmis är en innehållsskapare som har en passion för att skriva och skapa nya saker.

IPv4-only traffic to access the application in the application subnet. The approach reduces complexity for the application team and reduces the attack surface.Deploy Azure Front Door to provide global routing for web traffic.Azure Front Door capabilities include proxying IPv6 client requests and traffic to an IPv4-only back end, as shown here:These are main differences between the NVA approach and the Azure Front Door approach:NVAs are customer-managed, work at Layer 4 of the OSI model, and can be deployed in the same Azure virtual network as the application, with a private and public interface.Azure Front Door is a global Azure PaaS service and operates at Layer 7 (HTTP/HTTPS). The application back end is an internet-facing service that can be locked down to accept only traffic from Azure Front Door.In complex environments, you can use a combination of both. NVAs are used within a regional deployment. Azure Front Door is used to route traffic to one or more regional deployments in different Azure regions or other internet-facing locations. To determine the best solution, we recommend that you review the capabilities of Azure Front Door and the product documentation.IPv6 virtual network CIDR blocks:You can associate a single IPv6 Classless Inter-Domain Routing (CIDR) block when you create a new virtual network in an existing Azure deployment in your subscription. The size of the subnet for IPv6 must be /64. Using this size ensures future compatibility if you decide to enable routing of the subnet to an on-premises network. Some routers can accept only /64 IPv6 routes.If you have an existing virtual network that supports only IPv4, and resources in your subnet that are configured to use only IPv4, you can enable IPv6 support for your virtual network and resources. Your virtual network can operate in dual-stack mode, which enables your resources to communicate over IPv4, IPv6, or both. IPv4 and IPv6 communication are independent of each other.You can't disable IPv4 support for your virtual network and subnets. IPv4 is the default IP addressing system for Azure virtual networks.Associate an IPv6 CIDR block with your virtual network and subnet or BYOIP IPv6. CIDR notation is a method of representing an IP address and its network mask.

이 계산기는 가능한 네트워크 주소, 사용 가능한 호스트 범위, 서브넷 마스크, IP 범주 등 인터넷 프로토콜 버전 4(IP v4) 및 IPv6 서브넷과 관련된 다양한 정보를 반환합니다.IPv4 서브넷 계산기IPv6 서브넷 계산기서브넷은 IP 네트워크 (인터넷 프로토콜 그룹) 의 일부이며, 여기서 IP 네트워크는 인터넷 및 기타 유사한 네트워크에서 사용되는 통신 프로토콜 세트입니다. 이를 TCP/IP (전송 제어 프로토콜/인터넷 프로토콜) 라고 합니다. 네트워크를 최소한 두 개의 독립 네트워크로 나누는 동작을 서브넷이라고 하며 라우터는 서브넷 간 트래픽 교환을 허용하는 장치이며 물리적 경계 역할을 합니다. IPv6 사용은 2006 년 이후 꾸준히 증가하고 있지만 IPv4 는 가장 널리 사용되는 네트워크 주소 지정 아키텍처입니다. IP 주소는 네트워크 번호 (라우팅 접두어) 와 rest 필드 (호스트 식별자) 로 구성됩니다. Rest 필드는 지정된 호스트 또는 네트워크 인터페이스에 고유한 식별자입니다. IPv4 및 IPv6 의 라우팅 접두사는 일반적으로 CIDR (classless domain routing) 을 사용하여 표시됩니다. CIDR 은 네트워크 및 개별 장치에 대한 고유 식별자를 만드는 방법입니다. IPv4 의 경우 네트워크는 서브넷 마스크를 사용하여 표기할 수도 있으며, 서브넷 마스크는 계산기의 "서브넷" 열에 표시된 대로 점 10 진수로 표시되는 경우도 있습니다. 호스트 식별자와 달리 서브넷의 모든 호스트는 동일한 네트워크 접두어를 가지며 호스트 식별자는 고유한 로컬 식별자입니다. IPv4 에서 이러한 서브넷 마스크는 네트워크 번호와 호스트 식별자를 구분하는 데 사용됩니다. IPv6 에서 네트워크 접두사는 IPv4 의 서브넷 마스크처럼 작동하며 접두사 길이는 주소의 자릿수를 나타냅니다.CIDR 을 도입하기 전에 주소 범주 (포함된 IP 주소 범위에 따라 A, B 또는 C) 및 넷마스크에 따라 IP 주소에서 직접 IPv4 네트워크 접두사를 얻을 수 있습니다. 그러나 CIDRs 가 도입된 이후 네트워크 인터페이스에 IP 주소를 할당하려면 주소와 넷마스크가 필요합니다.다음 표는 IPv4 의 일반적인 서브넷을 제공합니다. 접두어 크기 넷마스크 서브넷당 사용 가능한 호스트 수 /1128.0.0.02,147,483,646 /2192.0.0.01,073,741,822 /3224.0.0.0536,870,910 /4240.0.0.0268,435,454 /5248.0.0.0134,217,726 /6252.0.0.067,108,862 /7254.0.0.033,554,430 레벨 a /8255.0.0.016,777,214 /9255.128.0.08,388,606 /10255.192.0.04,194,302 /11255.224.0.02,097,150 /12255.240.0.01,048,574 /13255.248.0.0524,286 /14255.252.0.0262,142 /15255.254.0.0131,070 클래스 b /16255.255.0.065,534 /17255.255.128.032,766 /18255.255.192.016,382 /19255.255.224.08,190 /20255.255.240.04,094 /21255.255.248.02,046 /22255.255.252.01,022 /23255.255.254.0510 클래스 c /24255.255.255.0254 /25255.255.255.128126 /26255.255.255.19262 /27255.255.255.22430 /28255.255.255.24014 /29255.255.255.2486 /30255.255.255.2522 /31255.255.255.2540 /32255.255.255.2550.

2025-04-09Generated subnets. Output. Sipcalc output is divided into sections and subsections. Each section starts with the string "-[type : INPUT] - n" where type can be one of int-ipv4, ipv6, ipv4. INPUT is one input option from the commandline and n is the number of the section that this input option has produced currently displayed. Currently the only input option that produces multiple output sections is an interface with multiple addresses. A subsection starts with the string "[IDENTIFIER]", where IDENTIFIER is an identifier for the subsection type. The subsection types are based on the used commandline options. Sections always en with the single character '-' alone on a line. Worth mentioning is also that sections can include not only subsections, but also other sections, this currently only happen when the -u and -s/-S options are used. Warnings/errors etc. can also be displayed in the form -[type : message]. Description of common output: [IPv4] Host address The given host address. Network address The first address in a given range, unusable for hosts under normal conditions. Network mask The network mask (netmask) used to specify the size of a given subnet, usually represented in three different formats: dotted quad (xxx.xxx.xxx.xxx) hex (0xnnnnnnnn) bits (/n where n >= 0 OPTIONS -a, --all Give all possible information about an address or interface, this is equivalent to giving the flags -b -c -i -n 0 for IPv4 and -e -r -t for IPv6. -b, --cidr-bitmap (IPv4) Display CIDR based bitmaps. -c, --classfull-addr (IPv4) Display classfull address information. -d, --resolve Enable name resolution. -e, --v4inv6 (IPv6) Display v4inv6 address information. -h, --help Display the commandline help. -i, --cidr-addr (default IPv4) Display CIDR address information. -I, --addr-int=INT Explicitly add an interface. This can be used to circumvent the sipcalc "smart parsing" of addresses/interfaces on the commandline. This can be useful if you for example for some reason have an interface with the same name as an actual address, eg. 127.0.0.1 or ::1 etc. See also: -4 -6. -n, --subnets=NUM Display NUM extra subnets (starting from the current subnet). Will display all subnets in the current /24 if
