Whois
Whois (pronounced as the phrase who is) is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information [1].
Implementation
Whois is first implemented on UNIX and is available for all operation systems. The implementation may vary in functionality.
Servers
|
Whois servers operated by Regional Internet Registries (RIR) can be queried directly to determine the Internet Service Provider responsible for a particular resource: [2]

Services
Is it possible to get Whois information for free? Yes and no.
- Yes for doing lookups using the unix whois clients using port 43.
- Yes for doing queries using the RESTful method/interfaces of the providers (if defined, see below).
- No for bulk lookups. The services are limited by the number of queries. The first 100-500 queries are for free. The next have to be paid. Example
Also the given information differs in quality. See the examples below especially the Whois CLI-Examples.
If you host your website on an external server, the owner may have closed port 43 for whois access. In that case you'll need an http-lookup without using port 43. A very popular and good service is provided by http://www.woisxmlapi.com. Unfortunately not for free.

IPv6 Addresses
The rapid grow of the Internet world wide has created a problem for the IPv4 IP-Addresses, the possible number of IP-Addresses has been reached.
Meaning there have to come a solution a larger number of unique IP-addresses the IPv6.
IPv6 addresses are classified by the primary addressing and routing methodologies common in networking: [3]
- A unicast address identifies a single network interface.
The Internet Protocol delivers packets sent to a unicast address to that specific interface. - An anycast address is assigned to a group of interfaces, usually belonging to different nodes.
A packet sent to an anycast address is delivered to just one of the member interfaces, typically the nearest host, according to the routing protocol's definition of distance. Anycast addresses cannot be identified easily, they have the same format as unicast addresses, and differ only by their presence in the network at multiple points. Almost any unicast address can be employed as an anycast address. - A multicast address is also used by multiple hosts, which acquire the multicast address destination by participating in the multicast distribution protocol among the network routers.
A packet that is sent to a multicast address is delivered to all interfaces that have joined the corresponding multicast group.
IPv6 does not implement broadcast addressing. Broadcast's traditional role is subsumed by multicast addressing to the all-nodes link-local multicast group ff02::1. However, the use of the all-nodes group is not recommended, and most IPv6 protocols use a dedicated link-local multicast group to avoid disturbing every interface in the network.
An IPv6 address consists of 128 bits.
For each of the major addressing and routing methodologies, various address formats are recognized by logically dividing the 128 address bits into bit groups and establishing rules for associating the values of these bit groups with special addressing features.
Unicast and anycast address format
Unicast and anycast addresses are typically composed of two logical parts:
- a 64-bit network prefix used for routing,
- and a 64-bit interface identifier used to identify a host's network interface.
General unicast address format (routing prefix size varies) bits 48 (or more) 16 (or fewer) 64 field routing prefix subnet id interface identifier
The network prefix (the routing prefix combined with the subnet id) is contained in the most significant 64 bits of the address. The size of the routing prefix may vary; a larger prefix size means a smaller subnet id size. The bits of the subnet id(entifier) field are available to the network administrator to define subnets within the given network. The 64-bit interface identifier is either automatically generated from the interface's MAC Address using the modified EUI-64 format, obtained from a DHCPv6 server, automatically established randomly, or assigned manually.
A link-local address is also based on the interface identifier, but uses a different format for the network prefix.
Link-local address format bits 10 54 64 field prefix zeroes interface identifier
The prefix field contains the binary value 1111111010. The 54 zeroes that follow make the total network prefix the same for all link-local addresses (Template:IPaddr link-local address prefix), rendering them non-routable.
Multicast address format
Multicast addresses are formed according to several specific formatting rules, depending on the application.
General multicast address format bits 8 4 4 112 field prefix flg sc group ID
The prefix holds the binary value 11111111 for any multicast address.
Currently, 3 of the 4 flag bits in the flg field are defined; the most-significant flag bit is reserved for future use.
Multicast address flags[4] bit flag Meaning when 0 Meaning when 1 8 reserved reserved reserved 9 R (Rendezvous) Rendezvous point not embedded Rendezvous point embedded 10 P (Prefix) Without prefix information Address based on network prefix 11 T (Transient) Well-known multicast address Dynamically assigned multicast address
The 4-bit scope field (sc) is used to indicate where the address is valid and unique.
There are special multicast addresses, like Solicited Node.
Solicited-Node multicast address format bits 8 4 4 79 9 24 field prefix flg sc zeroes ones unicast address
The sc(ope) field holds the binary value 0010 (link-local). Solicited-node multicast addresses are computed as a function of a node's unicast or anycast addresses. A solicited-node multicast address is created by copying the last 24 bits of a unicast or anycast address to the last 24 bits of the multicast address.
Unicast-prefix-based multicast address format bits 8 4 4 4 4 8 64 32 field prefix flg sc res riid plen network prefix group ID
Link-scoped multicast addresses use a comparable format.
CIDR
A detailed view in CIDR [5]
|
Every device connected to the Internet needs to have an identifier. Internet Protocol (IP) addresses are the numerical addresses used to identify a particular piece of hardware connected to the Internet. IP addresses are assigned to networks in different sized ‘blocks'.
The size of the ‘block' assigned is written after an oblique (/), which shows the number of IP addresses contained in that block.
The lower the number after the oblique, the more addresses contained in that “block”. The Classless Inter-Domain Routing (CIDR) is commonly known as the CIDR chart and is used by those running networks and managing IP addresses. It enables them to see the number of IP addresses contained within each “slash notation” and the size of each “slash notation” in bits. Currently, most ISPs assign /48 network prefixes to subscribers' sites (the End Users' networks). Because all IPv6 networks have /64 prefixes, a /48 network prefix allows 65,536 LANs in an End User's site. The current minimum IPv6 allocation made by the RIPE NCC is a /32 network prefix. If the LIR only made /48 assignments from this /32 network prefix, they would be able to make 65,536 /48 assignments. If they decided to only assign /56 network prefixes they would have 24 bits available to them, and so could make 16,777,216 /56 assignments. |

Web Crawlers
Website Crawler, the hard-working, lesser-known, essential component of a search engine.
A web crawler is a bot—a software program—that systematically visits a website, or sites, and catalogs the data it finds.
It’s a figurative bug that methodically locates, chews on, digests, and stores digital content to help create a searchable index.
