I am wondering what does it mean! Usually I use static IP address at work, as I have a local oracle database, our ISA firewall has “strict” rules, limiting IP ranges from downloading from internet etc.

Recent days I was shuttling between two branch offices and was forced to reset my IP settings to obtain DHCP addresses. Interestingly, twice I found that once I pick obtain IP address automatically option, the default gateway (Grayed out) is seen (refer the image) when I open the property console for IPV4 section.

The most interesting factor is, regardless my branch locations (we use 131.102.xx.xxx) where the third octect differs each network (C class), the DHCP settings shows ‘131.102.10.1’ as the default gateway.

Please check the image attached and if you have an explanation, please post it over here.
