Blocked for possible web abuse

The IP address you are coming from has requested an inordinately large number of pages in a short amount of time and has been temporarily blocked to conserve our resources. This often happens when people try to use web spidering programs to download large portions of the site. The block will be removed 24 hours after the latest period of high traffic. If you feel this IP ban was made in error, you can email [email protected].

IP Protocol Number List: nmap-protocols

This file maps the one-byte IP protocol number in the IP header into the corresponding protocol name. Example 14.6 is a typical excerpt.

Example 14.6. Excerpt from nmap-protocols
hopopt           0     HOPOPT      # IPv6 Hop-by-Hop Option
icmp             1     ICMP        # Internet Control Message
igmp             2     IGMP        # Internet Group Management
ggp              3     GGP         # Gateway-to-Gateway
ip               4     IP          # IP in IP (encapsulation)

The first two fields are the protocol name or abbreviation and the number in decimal format. Nmap doesn't care about anything after the protocol number. It is used for IP protocol scanning, as described at the section called “IP Protocol Scan (-sO)”. Fewer than 140 protocols are defined and users almost never modify this file. The raw data is made available by the IANA at http://www.iana.org/assignments/protocol-numbers.
