Router(config)#hostname TokyoTokyo(config)#

Host Name Resolutions
Host name resolution is the process that a computer system uses to associate a host name with an IP address.
Host names, unlike DNS names, are significant only on the router on which they are configured.

What are ACLs?
• ACLs are lists of instructions you apply to a router's interface to tell the router what kinds of packets to accept and what kinds to deny.
![Page 24: IS 340 Review Router 101 Brigham Young University-Idaho](https://reader035.vdocument.in/reader035/viewer/2022062517/56649f2a5503460f94c43866/html5/thumbnails/24.jpg)
ACLs must be defined on a per-protocol, per direction, or per port basis
ACL must be defined for each interface
ACL must be defined for each protocol enabled on the interface
ACLs control traffic in one direction at a time on an interface

Placing ACLs
Standard ACLs should be placed close to the destination.
Extended ACLs should be placed close to the source.
