Ethernet standards limit a LAN diameter to $500$ meters because longer distances would degrade $[$ Select $]["$TTL$",$ "traceroute $($tracert$)",$ "datagrams", "signal quality", "path MTU", "indirect", "direct", "collisions"$]$ and also would affect the detection of $[$ Select $]["$traceroute $($tracert$)",$ "indirect", $"$TTL$",$ "path MTU", "datagrams", "direct", "collisions", "signal quality"$].$

The ICMP is used to find the $[$ Select $]["$indirect$",$ "direct", "collisions", "path MTU", "traceroute $($tracert$)","$TTL$",$ "datagrams", "signal quality"$]$ by sending $[$ Select $]["$datagrams$",$ "collisions", $"$TTL$",$ "direct", "signal quality", "path MTU", "indirect", "traceroute $($tracert$)"]$ with the $$Do Not Fragment$$ flag set.

$[$ Select $]["$collisions$",$ "traceroute $($tracert$)",$ "direct", "datagrams", "signal quality", $"$TTL$",$ "path MTU", "indirect"$]$ uses ICMP to perform an expanding ring search, which involves sending a sequence of datagrams with the $[$ Select $]["$indirect$",$ "path MTU", "datagrams", "traceroute $($tracert$)",$ "collisions", "direct", $"$TTL$",$ "signal quality"$]$ field incremented in each successive datagram.

In wireless mobility, the foreign agent assigns a new address to a mobile unit. $[$ Select $]["$TTL$",$ "datagrams", "path MTU", "traceroute $($tracert$)",$ "indirect", "collisions", "signal quality", "direct"$]$ routing then sends the new address to the correspondent. $[$ Select $]["$traceroute $($tracert$)",$ "collisions", "datagrams", $"$TTL$",$ "direct", "indirect", "path MTU", "signal quality"$]$ routing sends the new address to only the mobile unit$$s home agent
