Rev 1.6.9 ip/ipv6 map-hostname {ip |ipv6} map-hostname no {ip | ipv6} map-hostname Maps between the currently-configured hostname and the loopback address 127.0.0.1. The no form of the command clears the mapping. Syntax Description N/A Default IPv4 mapping is enabled by default IPv6 mapping is disabled by default Configuration Mode Config History 3.1.0000 Role admin Example switch (config) # ip map-hostname switch (config) # # show hosts Hostname: switch Name server: 9.9.9.9 (configured) Name server: 10.211.0.121 (dynamic) Name server: 172.30.0.126 (dynamic) Name server: 10.4.0.135 (dynamic) Domain name: mydomain.com (configured) Domain name: lab.mtl.com (dynamic) Domain name: vmlab.mtl.com (dynamic) Domain name: yok.mtl.com (dynamic) Domain name: mtl.com (dynamic) IP 1.1.1.1 maps to hostname p IP 127.0.0.1 maps to hostname localhost IP 2.2.2.2 maps to hostname my-host IPv6 2001::8f9 maps to hostname my-ipv6-host IPv6 ::1 maps to hostname localhost6 Automatically map hostname to loopback address: yes Automatically map hostname to IPv6 loopback address: yes switch (config) # switch (config) # ping my-host-name PING localhost (127.0.0.1) 56(84) bytes of data. 64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.078 ms 64 bytes from localhost (127.0.0.1): icmp_seq=2 ttl=64 time=0.052 ms 64 bytes from localhost (127.0.0.1): icmp_seq=3 ttl=64 time=0.058 ms Related Commands show hosts Note • If no mapping is configured, a mapping between the hostname and the IPv4 loopback address 127.0.0.1 will be added • The no form of the command maps the hostname to the IPv6 loopback address if there is no statically configured mapping from the hostname to an IPv6 address (disabled by default) • Static host mappings are preferred over DNS results. As a result, with this option set, you will not be able to look up your hostname on your configured DNS server; but without it set, some problems may arise if your hostname cannot be looked up in DNS.
